Subject: [PATCH 1/2] query-py: Ensure reldep is from the same sack
When using two Base() modules, it is possible that a Reldep is
referenced across sack instances.
Example:
base1 = dnf.Base()
base1.read_all_repos()
base1.fill_sack()
base2 = dnf.Base()
base2.read_all_repos()
base2.fill_sack()
pkg = base1.sack.query().filter(name='glibc').latest()[0]
for req in pkg.requires:
base2.sack.query().filter(provides=req) // Should FAIL
The Reldep object from the "req" is sack-specific. This commit changes
the above into a failure condition by verifying that the Query and
Reldep come from the same sack. In the event that they do not, it raises
the following error:
"Direct dependency lookups must originate from the same sack."

Subject: [PATCH 2/2] Hawkey tests: Make the Query test per-sack
Following "query-py: Ensure reldep is from the same sack", it is
necessary to make Reldep use per-sack. This commit alters the Query
tests to create per-sack Query objects.
